io ho fatto questa procedura, ma non si è resettato niente:
This fix will do a factory reset of the receiver. It will probably resolve this issue in all modes.
1.Power on Transmitter.
2.Power on helicopter.
3.Pull back on right stick and hold.
4.Push the panic button and hold.
5.The swashplate will twitch. It takes about 5 seconds before you will see it level itself.
6.Release the right stick and the panic button.
That's it, your receiver has now been reset back to factory specifications.
Altri tentativi non li ho fatti

anche perchè non ne sento il bisogno dato che vola benissimo.
